The Rico Neck Saver is designed to be placed in the neck of your Alto Saxophone after use. Absorbent fibers wick the moisture in the neck stopping the performance being affect and giving it an overall longer life. The Neck Saver has a flexible shaft allowing it to conform to the contours of your saxophone neck. Neck Savers will help to eliminate moisture removing the moisture that cloths may leave behind. This means that your saxophone neck will be kept drier.
